That looks familiar, though as a rule we try to only ride up on ice. Your friend's tires must generate an impressive amount of grip because your normal studded tire would not allow anything close to what he was pulling in those video shots.

What you describe is what "normal" people do in winter here as well. Normal Nokian studded tires for trail-riding. Several people here make these homemade things just to check how it works, or for that one day at the skilifts during winter.

Nokian Freddiez Revenge don't work for riding like this at all, they would let go easily. On "normal" trails they hook up very well though. Homemade studds like this would not work for trailriding at all. The fireroad he rides down here is pretty steep too, much steeper than it looks. It is usually used for climbing to the trailhead during summer, a 20-30 minute climb :-)
